动态获取权限工具类（方法）

直接上代码，大家应该能看懂

    private static List<String> permissionList;
    public static void getPermission(Activity context,String... permission) {
        permissionList = new ArrayList<>();
        for (int i = 0;i<permission.length;i++){
            if (ContextCompat.checkSelfPermission(context,permission[i])
                    != PackageManager.PERMISSION_GRANTED){
                permissionList.add(permission[i]);
            }
        }
        if (permissionList.size()>0){
            String[]  permissions = new String[permissionList.size()];
            for (int i = 0;i<permissionList.size();i++){
                permissions[i] = permissionList.get(i);
            }
            ActivityCompat.requestPermissions(context, permissions,1);
        }
    }

把上面的代码复制到自己的工具类里面然后调用就行了，调用方式

BaseTool.getPermission(this, android.Manifest.permission.CAMERA,
                android.Manifest.permission.WRITE_EXTERNAL_STORAGE,
                android.Manifest.permission.ACCESS_FINE_LOCATION);

如果有什么问题希望大家共同探讨
